Although this is only one of at least forty miracles during the exodus and wilderness wanderings, it is especially important as a prophecy of the coming work of Christ on the cross. “As Moses lifted up the serpent in the wilderness,” said Jesus, “even so must the Son of man be lifted up: That whosoever believeth in Him should not perish, but have eternal life” (John 3:14,15).
